Description

BACKGROUND OF THE INVENTION The present invention relates to compositions having an antistatic effect for painting, polishing, preferably coating, polishing, treating and hydrophobising wood, plastic and metal surfaces after cleaning.

Many of the varnished and painted surface objects lose their gloss and shine due to the lack of regular care and maintenance, and they absorb dust and moisture due to cracks on the surface. The increase in the moisture-absorbing capacity causes significant damage primarily to objects stored outdoors and thus exposed to weather conditions, such as cars and garden furniture. Objects with polished and painted surfaces held outdoors are subject to much greater stress than those in the enclosure. The formation of micro-cracks due to temperature fluctuations is very significant. These cracks are hardly visible to the eye, but are already suitable for curing moisture and storing it for a long time. This makes them the starting points for various corrosion processes.

The durability of the paint layer is also greatly reduced by the ultraviolet radiation of the sun's rays, which primarily causes the paint to "chalk". All these environmental influences necessitate the regular treatment of the surface coatings of painted and polished objects, especially cars.

Dust deposited on the surface coating layer also has a detrimental effect. Its aesthetic effect is also unfavorable, but it is more important that the dust layer deposited on the surface absorbs the humidity of the air and thus provides higher humidity in the immediate vicinity of the paint layer. This increases the likelihood of corrosion processes occurring.

Due to the importance of surface treatment of polished and painted objects, especially furniture and cars, a wide variety of products are marketed. Most of these are waxes of vegetable or animal origin (carnauba wax, beeswax) or mineral waxes. contains artificial wax. Each formulation also contains a solvent, primarily an apolar solvent such as petroleum or turpentine, but also emulsions in aqueous solutions are common.

In addition, various compositions may also contain other substances such as silicone oil, resin, perfume, amines.

Some of the very large number of formulations are described which appear to be important in determining the present state of the art.

I patent).

After this brief review of the literature, there are many ways to improve the quality and usability of toner products. The use of silicone derivatives is particularly important and of great importance. These compounds have a good effect on the surface of treated surfaces because of their highly water repellent properties, protecting the treated surface for a longer period of time from the adverse effects of moisture, but also good in eliminating surface scratches and damage. However, an undesirable side effect of the use of these agents is, on the one hand, the increased dustiness of the treated surface, partly due to the ability of the silicone oil to bind, and, on the other hand, the water repellency of the compositions.

We have discovered that if silicone oil

A small amount of antistatic surfactant is also added to the composition for treating painted or polished surfaces containing 194,582, which not only eliminates the above drawbacks, but unexpectedly results in a composition with significantly better water repellency properties than those expected for each component.

SUMMARY OF THE INVENTION: Silicone antistatic compositions for the treatment, polishing, post-cleaning and water repellant treatment of painted and polished, preferably wood, plastic and metal surfaces, containing from 0.05% to 5.0% by weight of natural or artificial waxes or mixtures thereof, 0.0-3.0% by weight of perfume, 0.0-96.0% by weight of organic solvent, 96.0-0.0% by weight of water and 0.0-5.0% by weight of emulsifier, characterized in that: 0.5 to 7.0% by weight, based on the total weight of the composition, of one or more silicone oils, preferably open-chain dimethylpolysiloxane containing methyl or phenyl groups as the substituent, and 0.05 to 3.0% by weight of nonionic surfactant with antistatic effect, preferably they also contain polyethylene glycol fatty acid monoester.

A study of the surfactant literature shows that they have the following properties: wetting effect, dispersing action, emulsifying action, foaming ability, washing effect.

The detergent is the most valuable property of the surfactants because they are sufficiently soluble in water, reduce the surface tension of the surface to be washed, thereby providing a good wetting effect, dispersing and emulsifying the contaminant and keeping it in solution. All of these properties apply to nonionic surfactants separately.

It is therefore natural that surfactants such as nonionic surfactants, due to their excellent detergent effect, are present in almost all detergents and cleaning compositions, but are also useful in formulating pesticides because of their dispersing and emulsifying properties.

The situation is different, however, when it comes to a surface treatment composition 40 which is used to treat or preserve the surface of objects that are poorly resistant to water. Here, the wetting effect of the surfactants is detrimental, so their use seems to be contrary to the purpose of the preparation. 45

The aim of the present invention was to provide a composition which is better and more durable than the known compositions against the harmful effects of moisture and which preserves the treated surface well. While the advantageous properties of the use of silicone oil are known in the literature, the choice of nonionic surfactant is not at all obvious for a formulation whose primary purpose is to protect the surface from moisture rather than to clean it. Here, we would like to refer to what surfactants 55 say, that surfactants are excellent moisturizers and promote good contact between the treated solid and water.

The essence of the present invention is to realize that by using only a few representatives of nonionic surfactants in our formulations which differ from other surfactants in that they have known antistatic properties, not only can the said wetting effect be overcompensated, but surprisingly much more. better water repellent owner- θ5

up to certain formulations may be expected from certain components. · '&

The ionic surfactants we employ do not pre-enhance the water repellency of the surface unless the compounds having the property are present in the surfactant. Thus, the subject matter of the present invention is limited to the use of nonionic surfactants with known static properties and the other nonionic surfactants as having substantially different effects are not within the scope of the present invention.

In our product, not the additive effect of the individual components, but their synergistic effect is the most important property of the formulations, their water repellency.

This effect is non-additive because the non-ionic surfactants used as antistatic agents cannot be used as surface water repellents per se. Their known application is not related to surface hydrophobization and are known in the literature to have a wetting effect. Our test results also confirmed this.

Antistatic agents are widely used in many areas of the industry, particularly in the textile industry. In the production of textiles made from synthetic yarns, they are effective in weaving, wrapping and finishing as anti-adherent and anti-caking agents. Antistatic agents are also useful for the treatment of underwear and outerwear of carpets, carpeting, curtains, and synthetic yarns. We are not aware of their use for painted and polished wood, plastic and metal surfaces.

Other ingredients used in our antistatic cleaning compositions are known and have been used for similar purposes.

Natural or artificial waxes include waxes of vegetable, animal or mineral origin, such as carnauba wax, beeswax, montan wax. Examples of artificial waxes include oxidized paraffin esters and oxidized montan wax esters.

Suitable silicone oils are those manufactured by the Fine Chemicals Cooperative. These are open-chain, unbranched dinethyl polysiloxanes in which the free valencies of the silicon atoms in the polysiloxane chain are methyl or methyl. phenyl groups.

Their molecular weight and thus their viscosity depend on the degree of polymerization of the compound. Their properties are molecular weight and they change only slightly with the change in viscosity. Examples of suitable silicone oils are silylol M-50 (viscosity: 5 · 1CF ^S m ² / s, density: 0.95-96 g / ml) silorol M-100 (viscosity: 1CT ⁴ m ² / s, density: 0, 96 g / ml Silorol M-350 (viscosity: 3.5 · ΙΟ ^-4 m ² / s, density: 0.96-0.97) Silorol M-500 (viscosity: 5 · 10 ⁴ m ² / s, Density: 0.96-0.97) and Silicol M-1000 (Viscosity: ΚΓ ³ m ² / s, Density: 0.96-97) or Silicol F-200 (Viscosity: 2 · ΚΓ). ⁴ m ² / s, density: 1.06 g / ml) Szilorol F-500 (viscosity of 5 · 1CT ⁴ m ² / s, density: 1.07 g / ml) brand phenyl silicone oils.

Preferably, the perfume may be an alcoholic solution of lavender oil, or similarly used in the cosmetics industry.

194,582

Naturally, fragrances are only part of our furniture care products.

Suitable solvents are all solvents in which the formulation components, waxes, silicone oils, are well soluble and do not attack the paint surface to be treated. Preferred examples are: turpentine, white spirit, synthetic paint solvents, carbon tetrachloride, alcohols.

Non-ionic materials widely used in the textile industry are used as antistatic agents, such as Evistat-MF, a combination of monoesters of polyethylene glycol grade 18 with various fatty acids, or Softanun-P6, a grade 6 polymer of polyethylene. fatty acid monoester.

The invention is illustrated by the following examples:

Example 1: Place a 250 ml beaker on a magnetic stirrer and weigh:

1.0 g methyl silicone oil (Silorol M-100)

1.0 g Evistat MF au pure teakine

4.0 g of Ipamin SG-P6 emulsifier

1.5 g of a perfume dissolved in ethanol and

10.0 g of water

With vigorous stirring, a dense, homogeneous emulsion is formed and then slowly, in small portions, 82.5 g of water are added with constant stirring.

A medium-dense milky emulsion is obtained which is well suited for coating furniture surfaces and creating a semi-gloss finish.

Example 2: Place a 250 ml beaker on a magnetic stirrer and weigh:

4.0 g B-27 Wax (Danube Oil Oil Shoulder) (lp = 60 ° C)

1.0 g of carnauba wax (melting point = 82-82.5 ° C)

1.0 g paraffin (bp = 58-60 ° C)

3.0 g phenyl silicone oil (silorol F-200)

1.5 g of Evistat MF antistatic

With gentle heating, 150 g of carbon tetrachloride are added and stirred until completely dissolved. A clear solution is obtained which leaves little wax on cooling. Shaken before use, it is well suited for coating, hydrophobising and polishing car surfaces.

Example 3: Place a 250 ml Ertcnmcyer flask on a magnetic stirrer and weigh:

5.0 g of wax B-27 (Danube Oil Oil Shoulder) (lp = 60 ° C)

3.0 g of methyl silicone oil (Silorol M-350) and

7.0 g of turpentine

While stirring, heat to 40-45 ° C until a homogeneous solution is obtained. At this point, stirring is discontinued, and 85 g of white spirit are added slowly. After the addition of white spirit, 1.0 g of Evistat MF antistatic and 1.0 g of ethanol dissolved in the homogeneous solution were added and stirred for a further 5 minutes. A clear solution is obtained which is excellent for preserving and polishing furniture surfaces.

In the following, the experiments and test results which have been performed to prove the synergistic water repellency of our preparations are described. For ease of evaluation, 1 g to 1 g of each of the test silicone oils and the antistatic agent were taken. For a more uniform application of the components, solutions of organic solvents were prepared from each component.

Our experiments were carried out with sample solutions containing the following amounts of substances. Each sample solution was prepared using 100 g of carbon tetrachloride.

Sample number

1. 1 g of Silorol Μ-100 Silicone Oil

2. 1 g Silicol F-200 Silicone Oil

3. 1 g of Softamine P6 antistatic agent

4. 1 g of Evistat-MF antistatic

5. lg Silorol F -200 Silicone Oil and 1 g Softamine-P6 Antistatic

6. 1g Silorol Μ-100 Silicone Oil and 1g Evistat-MF Antistatic

11. 1 g Silorol M-100 Silicone Oil 1 g Evistat-MF Antistatic and g Carnauba wax

12. lg Silorol Silicone oil F-200 g g Softamine P6 antistatic and g Carnauba wax

To further characterize the assay, formulations were also performed to determine synergistic water repellency that did not contain wax. In this case, the synergistic water repellent effect was more clearly demonstrated, but this beneficial effect was shorter in the case of wax applications. The reason for this phenomenon is that the wax affixes the other components to the surface in a favorable manner. mainly it. antistatic agents, they are able to exert their effects over time.

However, our experiments with non-wax formulations are important because their use has been able to screen out the water repellency effect of waxes which degrades the synergistic effect.

In our experiments, 400 cm ² dye-coated metal sheets were applied each at an angle of 10 ° to which a uniform amount of test sample (5 to 5 ml) was applied to a thoroughly cleaned surface, and after 10 minutes the surface was wiped with a soft cloth. The study time was 20 days. During this time, the metal sheets under investigation were kept outdoors, under conditions of natural effects such as rain, dust, wind, sunshine, etc..

The basis of our measurements is the water permeability of the examined surfaces

-4194 582. The tests were carried out by spraying 500 ml of water from the surface of the metal plates under test with a fine nozzle at 5 day intervals.

After spraying with water, the sheets were rested for 10 minutes, during which time excess water dripped. 5 We then measured the percentage of water retained on the surface using a square mesh method.

The synergistic water repellency was demonstrated using Colby's formula: (Weeds 15, jq 1967.1 20-22)

E, - ^X1 ' ^Y1100 where: Xi = the effect of Compound A on dose p 15

Y, = effect of Compound B at dose q Ej = expected effect of Compound A + B at p + q dose Er = measured effect of Compound A + B at p + q dose

In this case, the values of Ej and Er are the expected and the expected surfaces of the examined surfaces. measured moisture content as a percentage. The effect is synergistic if E1 is greater than ER, i.e. Ej - Er = positive number. Our results are summarized in two tables. The first 25 tables show the results for non-wax formulations.

The numbers in the table represent the wetted surface area as a percentage.

Table 1 summarizes the results of studies where wax was used.

Based on the test results, the synergistic effect of the samples 2, 3 and 5 is obtained according to the Ej-Er formula in the following order of measurement times:

E1-Er = 1.76 5.64 7.15 8.40 9.17

Analyzing the results obtained with samples 1, 4 and 6 in a similar manner:

E1-Er = 1.60 4.58 6.28 7.70 7.80.

Given that the numerical values obtained are positive numbers, a synergistic effect can be demonstrated as a result of the assay. The test results also show that the synergistic effect gradually increases with the exposure time of the test samples.

The following table shows the results obtained using the wax.

Based on the test results, the results obtained with Samples 7, 10 and 11 are used to test the synergistic effect in the following order of measurement times:

E1-Er = 0.73 1.62, 4.44 5.85 5.02

Performing the calculation in the same way as the results of samples 8, 9, 12 ':

E1-Er = 1.06 1.18 4.88 5.90 6.08.

Again, the calculations made with the results of each table give positive numerical results justifying the synergistic effect. The effect is increasing over time, but is not as characteristic as calculated from the results of Table 1, which is due to the effect of the wax applied. The increasing synergistic effect over time is probably due to the dissolution of some of the wetting agent surfactant from the surface layer over time, resulting in optimum water repellency in the wax layer.
